Matelas Comfort Light SI Women Sea To Summit

Technologies used:

• Delta-Core construction

Delta Coring technology reduces the thickness and lightens the self-inflating mattress while maintaining maximum comfort.
Design and manufacturing techniques optimize the process by removing 40% of the original foam volume. The material used is strong and durable.
The distribution of the foam on the surface of the mattress has been studied so as to obtain good performance for the criteria of weight, comfort, and conservation of body heat.
The small vertical "Delta Core" in the areas of body contact (shoulders, hips and feet) prevent your body from cooling down.
The larger "Delta Cores" lighten the mattress and reduce the bulk for transport.

• Material 30D Polyester with laminated TPU

The materials used, 30D polyester and laminated TPU guarantee a long life to the mattress.



• Multifunction valve

The Sea To Summit valve makes it easy to inflate and deflate the mattress. A non-return valve makes it easy to inflate the mattress, without loss of pressure. The flap, with a simple press, offers the possibility of precisely adjusting the hardness of the mattress (deflation step by step).
By removing the cap, deflation is very fast.



• Pillow Lock System

The hook-and-loop PillowLock fastener secures the pillow so it stays in place all night...




Measurement of the R-Value thermal resistance of Sea To Summit mattresses:

The R-Value is used to measure the thermal efficiency of a mattress.
It corresponds to its ability to retain body heat in order to prevent it from spreading to the ground. Until now, manufacturers of sleeping equipment defined their own test methods to evaluate this resistance. The results were therefore difficult to interpret.

The new ASTM F3340-18 standard provides a methodology for measuring the thermal resistance of a mattress. Thus, it is now possible to compare the thermal performance of different models.
ASTM is an independent, international standards body.
